Composite structure manufacturing method and composite structure manufacturing device

Abstract

A composite structure manufacturing method comprising: a lamination step in which a plurality of fiber-reinforced resin sheets are laminated to form a plate-shaped laminate; a pressing deformation step in which a third roller or similar, which rolls along a plate surface of the laminate, is used to press the plate surface of the laminate, thereby forming a recessed section or a protruding section in a prescribed section of the laminate; a short direction deformation step in which, after the pressing deformation step, the laminate is deformed in the short direction to make the long direction cross-section into a prescribed shape; and a long direction deformation step in which, after the pressing deformation step, the laminate is deformed in the long direction to make the short direction cross-section into a prescribed shape.
